According to Skymet Weather, there is a cyclonic circulation near the equator over the southern central parts of the Arabian Sea and the adjacent Indian Ocean. A trough is formed from this system up to the Comorin area. A cyclonic system is over the southwestern parts of the Bay of Bengal and adjoining Sri Lanka coasts.
A new cyclonic circulation has developed over southern Rajasthan. At the same time, a trough has formed from the northern parts of Punjab to the northeast Arabian Sea through Rajasthan and Gujarat.
During the next 24 hours, the weather will remain mostly clear and dry in almost all the regions of the country, although light to moderate rainfall activity may occur at one or two places in Arunachal Pradesh.
Cold day conditions will prevail at one or two places in eastern Uttar Pradesh, Bihar and West Bengal. There is a possibility of dense fog in the Gangetic plains during the next 24 hours, which will affect normal life.
5-Day Nationwide Weather Forecast
According to the India Meteorological Department (IMD), conditions are becoming favourable for the cessation of Northeast Monsoon rains over Tamil Nadu, Puducherry & Karaikal, Kerala & Mahe, and the adjoining areas of coastal Andhra Pradesh & Yanam, Rayalaseema, and South Interior Karnataka on January 19, 2021.
However, parts of South India will experience thunderstorms due to a feeble cyclonic circulation around Sri Lanka, but the affected areas will only be limited to the southern end of the subcontinent.
At the opposite end, it will likely snow from Friday afternoon in the high altitude areas of Jammu & Kashmir due to a western disturbance (WD). Further, Jammu is also likely to experience heavy rain in low altitude areas, and heavy snowfall in the high altitude areas on Saturday.
In fact, the IMD predicts that under the influence of the WD’s interaction with low-level easterlies from January 23, scattered to widespread rain/snow is likely over the Western Himalayan Region during January 22-24, and isolated rain/thundershowers are possible over the adjoining plains of Northwest India during January 23-24.
Meanwhile, both daytime and nighttime temperatures across the Indo-Gangetic Plain will be generally higher than normal. While the daytime temperatures may near normal due to the strong northwesterly winds in the lower layers, the nighttime mercury levels are expected to be in single digits.
Further, the reversal of winds from easterly to westerly/northwesterly has started over the plains of North India. Accordingly, the minimum temperatures are very likely to fall by 2-4°C during the next three days, leading to cold wave conditions in isolated pockets over East Uttar Pradesh, Punjab, Haryana, Chandigarh, and Delhi during January 19-20, and over West Uttar Pradesh and north Rajasthan during January 19-21.

As for the central part of the Western Himalayan region, including Nepal, the temperatures will continue to be extreme or quite higher, at least until the end of January.
Lastly, the IMD has forecast that dense to very dense fog is expected in isolated pockets over Bihar, while dense fog is possible in the isolated pockets over Uttarakhand, Punjab, Haryana, Chandigarh, Delhi, East Uttar Pradesh, Rajasthan, and Odisha during the next 24 hours. A significant decrease in spread and density is expected thereafter, till the morning of January 22.
Cold Day conditions are also on the cards in isolated pockets across Punjab, Haryana, Chandigarh, Delhi, Uttar Pradesh and Bihar during the next 24 hours.

In Tuesday, isolated thunderstorms are possible over coastal Tamil Nadu. In the morning, very dense fog is likely over the Indo-Gangetic Plains, while dense fog is expected over western Assam, coastal Odisha, eastern Andhra Pradesh, and around Bangalore.
